Calibration Offset Ranges

Reversed Thermocouple Detection

Choose whether to enable polarity checking for thermocou-
ples. If the controller detects a reversed thermocouple, it
activates an alarm and sets the loop to manual mode at the
power level indicated by the Sensor fail heat output or Sen-
sor fail cool output
parameter in the Output menu.

Values: on (1) or off (0). Values in parentheses are for seri-
al communications and LogicPro, and are stored as the first
bit of the word at this address, so set or read only that bit.
Default: on (1)
Modbus Address (Loops 1 to 8): 44443 to 44450, first bit
Parameter Number: 86
LogicPro Driver: Database
LogicPro Address (Loops 1 to 8): 86.1 to 86.8, first bit

Display Format

For a process or pulse input, choose the range and the num-
ber of decimal places for the process variable and related
parameters. Choose a precision appropriate for the range
and accuracy of the sensor.

Values: See Table 5.9
Default: -999 to 3000 for a process input, -9999 to 30000 for
a pulse input
Modbus Address (Loops 1 to 9): 40666 to 40674
Parameter Number: 41
LogicPro Driver: Database
LogicPro Address (Loops 1 to 9): 41.1 to 41.9
